Worse yet, a lot of compressors have oil in their air. You can attached a dryer/filter to
the compressor outlet to block that. Compressors intended for air brush use tend to be
set up that way, and/or use a mechanism that doesn't use oil (such as a diaphragm
pump).

I should perhaps have mentioned that the idea is to flush the remaining
water or alcohol out by blowing, not evaporate it like your hairdresser
would :-) And you ought to use dry air, ideally - most compressors have water in their
air.
